Benchmarks: CD Speed: CD-R, CD-RW, DVD-ROM

Nero's CD Speed burn tests are done twice, once
with a CDR rated to 1x-52x burn speed, and a CD-RW rated to 4x-32x. Each disk
was test with files of about 640MB in size. This test is done by simply placing
blank recording media into the burner and running CD Speed the
software will detect if it is CD-R or CD-R/W media and run the
appropriate tests.

I was a
bit surprised to see that the
AOpen 5232 Combo drive could not reach its top speed of 52x despite having compatible media in
the drive.... We're actually able to just break the 32x speed barrier on the CD-RW side
of things.

CD Speed can also read DVD-ROM discs showing you
maximum transfer speeds, access times and CPU utilization. The DVD data disc has
about 3.78GB of data on it and is a retail DVD-ROM disc, not burned on a DVD-/+R
disc.

Again
the AOpen 5232 Combo is extremely fast, highest average speed we've ever seen but
for some reason access times are quite high, with CPU usage jumping to
50%!
